From publisher blurb:
During development of White Lies, we tended to overthink things. Game balance... difficult and elusive. Especially in a world when a bullet can end a rookie agent in a single moment. In any given session, it may be your bluffing skills which win the day. Or your investigative prowess. So game balance becomes a bit of a complex subject.
In this PDF, which we're giving you for free (though feel free to encourage us with any donation you'd like), you can use the same system we used to create the character classes presented in White Lies. It also has a few behind-the-scenes tidbits you might find interesting if you're interested in developing a roleplaying game (OSR or otherwise).
